Keeping an eye on all user activities

I am responsible for administering 6 Tru64UX servers.

I need to keep an eye on all the commands executed by all the users.

Is there a way where I can save the commands executed in a seperate folder and then keep checking the list every now and then.

How can do it ?

You can use lastcomm

I used that command to track my users on AIX RS6000 Server

http://btrcx1.cip.uni-bayreuth.de/cgi-bin/manpages/lastcomm/8

it outputs information about all previously executed commands that are recorded in the /var/adm/pacct file in reverse chronological order.

My pacct file is empty.

how do I ensure that the file is populated

start the accounting proccesses.

for a howto for aix look for the following red book on ibm website.
SG24-6020-00

the title is "Auditing and Accounting on AIX"

For Tru64, try the Auditing the system documentation (section 3 in the link).

History is a great way to take a look at what people are doing. Should they require root access, use sudo, and enable verbose logging. To show what files are open, try losf. And from the ole' command line, w works like a champ.
